Not a bad venue at all.
Yes it is pretty small, but imo that contributed to the intimate experience I had last night.
Yes people are drinking and there are occasional spills, the floor could get sticky but i don't see it as too big of an issue.
With few exceptions, people are generally mindful of personal space.
Apart from that, the tickets are usually very reasonable ($30), the sound system was pretty nice, and lighting etc everything contributed to an amazing experience. Would come back again if a band I like is playing here.
